Serial No. 794,755.

To all whom it may concern Be it known that I, WVIL IAM B. BARCUS, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Loaf-Forming ll lachines, of which the following is a specification.

This invention relates to certain new and useful improvements in loaf forming machines which are used for the purpose of shaping a batch of dough into a loaf.

The object of my invention is to provide a new and improved machine of. this kind which is simple in construction, strong, ef fective in use and rapidly converts a batch of dough into a perfectly molded andshaped loaf ready for the oven. I

In the accompanying drawings in which like letters of reference indicate like parts in all the figures:--Figure1 is a plan view of my improved loaf forming machine, parts being broken away. Fig. 2 is a side view, parts being broken away. Fig. 3 is a front end View, parts being broken away. Fig. 4 is a rear end view, parts being broken away. Fi 5 is a diagrammatic view showing the relation. of the several rollers and showing the sheeted dough and the loaf formedfrom the-same, in section in various positions. Fig. (3 is a vertical transverse sectional view through the loaf forming rollers and the side plates between which they are mounted, on the line a2m of Fig. 2.

The entire mechanism is mounted in two longitudinal upright side frames 1 which support all the several parts. At the front end of the machine, that is at the end at which the batch of dough is introduced, a main drive shaft 2 is mounted in the side frames 1 and this shaft carries a cog wheel 3 and a belt pulley 3 which is driven from a suitable source of power. On this-shaft is also mounted a feed roller A, the length of which roller is equal to about the distance between the side frames andwhich roller is mounted centrally between the side frames. Above this roller A a hopper l is mounted into which hopper the batch of dough is fed. A flour compartment 5 is formed at the lower end of the hopper 4 and is directly above the roller A and at the top of the hopper 4 another flour compartment 6 is formed which is directly above the roller B, between which rollers A. and B the batch of dough passes from the hopper, to be sheeted. The

cog wheel 3.

roller B is mounted upon a shaft 7 between two uprights 8 of the machine frame, which shaft 7 carries a cog wheel 9 engaging the The shaft 7 also carries a grooved pulley 10 over which an endless belt orrope 11 passes which rope or belt also passes over a grooved pulley 12 fixed on a shaft 13 mounted in the top of the standards 8 of the main frames. On this shaft 13 there is also fixed a grooved pulley 14L over which an endless belt or rope l5 passes which also passes over two pulleys 16 and 17 mounted between two bars 13 extending lengthwise of the frame and supported at the front ends by the shaft 13 which passes loosely through said side bars 18'and at the rear'ends by stand ards 1.9 on two side bars 20 of the frame 22 having laterally projecting arms23. The endless belt or rope 15 passes under a grooved pulley 2st mounted in the frame The main shaft 2 also carries a grooved pulle 1 over which an endless belt 26 asses which also passes over a grooved pulley 28 on a shaft 29 mounted in the main frame 1 and carrying a roller G which'is adjacent to trally and in said frame three rollers D, E

and l? are loosely mounted as are also the supplemental friction drive roller d. between and above the large rollers D and E and the friction roller betweenand above the fric-, tion rollers E and F so that the rollers and F- are driven from the, central roller E frictionally by means of the friction rollers (Z and 7", said rollers E and F and the friction rollers (Z and all being mounted inthe frame so that they are mounted to move together. as the said frame 35 is supported centrally by the shaft 33 of the central roller E, the front roller D and the rear roller F can swing up and down, the frontrollers swinging down when the swings up and vice versa.

In a horizontal member 36 of each side frame 1 three rollers G, H and J are mounted parallel Wltll each other and beneath the frame 35 and these three rollers rear roller I F D, Eand F and therollers G, H and J are all of the same length and parallel. Between the rollers C and G and the rollers G and H and the rollers H and J the three friction rollers g, h and j respectively are mounted between the bars 60 of the main frame and are in frictional contact with the rollers C, G, H and J and as the roller C is driven positively by the endless belt 29 from the main shaft, he rollers G, H and J are driven frictionally from the roller 0 by means of said friction rollers g, h and j.

Between two side plates 38 in the main frame a series of six rollers (more or less) K, L, M, N, O and P are mounted loosely that is to say, they do not have any end journals but the plates 38 extend almost up to the top of the ends of the said rollers. These drums or rollers K, L, M, N, O and P are all constructed alike and I will describe only one of them by referring to Fig. 6 which shows the roller 0 in longitudinal section. Each roller is provided at each end with a head i0 having a central boss ll on the outer side which boss rests loosely on the inner face of the side plate 38. To

' each head a0 a cylindrical section 42 is secured and the two sections 42 can telescope into a central tubular section at?) which is secured to a ring at having a cross piece on a stud of which a cog wheel l6 is loosely mounted and engages two opposite racks s? projecting through the cylindrical v sections l2 from the heads *0. Between each head so and the central frame 45 a volute spring 4:8 is held by studs passing from the inner sides of the head l0 and from the side edges of the cross piece 45 into the open ends of the volute spring. l/Vhen the two side plates 38 are pressed toward each other the volute springs l-S are compressed and the cylindrical section's l2 telescope into the central cylindrical section 43 and the racks ii? and pinions or cog wheel t keep the parts properly centered and re lated. When the plates 38 are moved apart to lengthen the said rollers the expanding volute springs move the outer two telescoping sections outward. Each side plate 38 is pr vi led at each end at the bottom with a wing e9 in which wings two transverse shafts are mounted. At the sides of the main frame these shafts pass through the main frame and on one projecting end is fixed a worm wheel 51 which worm wheels engage the worms on the ends of the h0rizontal shaft 53 suspended from the main frame by, sleeve brackets 5a. A crank handle is provided. on said shaft 53 at the rear end of the machine. The shafts 50 are provided with a right and left hand screw thread56 and 57 which pass through correspondingly threaded sleeves 58 and 59 in the bottom parts of the side plates 38 so that by turning said crank handle the lengthening them. Between the said side plates 38 and beneath the rollers K, L, M,

N. O and P six rollers, Q, R, S, T, U and W are mounted in the said side plates 38 and these rollers are all alike and of these rollers the roller Q is shown in longitudinal section in Fig. 6. They are, constructed like those of the upper tier of rollers with the exception that each end head 56 has a pivot 57 mounted in a side plate 38 and having ahead 58 on the outer end of the pivot so that the telescoping sections are compelled. to move with the side plates 38. The racks 47, the pinion l8, the central cross piece 45 and the telescoping and central sections are all present as described above. Between the rollers Q, R, S, T, U and a series of friction rollers g, 1", s, t, u and w are mounted in the longitudinal bars 60 of the main frame and contact with said rollers Q, R, S, T, U and W as shown in Figs. 2, 3 and a. The roller Q is in contact with the frictionroller Q which is also in contact with the roller j, see Fig. 2. The rollers K, L, M, N, O and l are suspended from two endless bands (31 preferably made of sheet steel, which bands pass over the pulleys (i2 and 63 on the frame 22, over the pulleys G l and 65 directly beneath the pulleys 62 and 63 and alternately under the rollers K, L, M, N, O and P and over the pulleys 65, 66, 67 and 68 and also over pulleys (39 which are fastened on the ends of the shaft 70 in the frame 22. Bearing blocks for the pulleys 69 are adjustable in the slot 71 of the frame 22 and can be adjusted by a screw 72 to tighten the belts G1. The side plates 38 are moved a greater or less distance from or toward each other and the rollers K, L, M, N, O, P, Q, R, S, T, U and between said side plates are lengthened or shortened in the manner pre viously described according to the desired length of the loaf. The directions of rotation of the several rollers are indicated by the arrows in li'ig. 5. It will be seen that the upper tier of rollers D, E, F, K, L, M, N, (l and P all rotate in the same direction which is the same direction of rotation of the lower tier rollers A, C, G, H, J, Q, R, S, T, U and W. The first upper roller B which is a feed roller, rotates in the inverse direction of all the other rollers. It will be observed that the pulleys 10 and 30 on the shaft 2 and 7 respectively are smaller than the pulleys on the shafts l2 and 33 respectively, whereas the pulley 25 on the shaft 2 and the pulley 28 on the shaft 29 are of the same size so that thereby all the rollers of the upper tier except the first roller B are rotated at about half the speed of the rollers of the lower tier.

The operation .is as follows :-The dough from the hopper passes between the rollers A and B and is converted into a sheet which is supported and carried forward by the first two lower rollers C and G and then its inner end encounters the roller D which turns the end of the sheet in the direction toward the front end of the machine and as the lower surface of the dough rests upon rollers which at their top turn in the direction from the front to the rear end of the machine and the upper surface of the dough encounters the vbottom parts of the upper rollers which bottom parts move in the direction from the rear to the front of the machine and as the lower rollers move with almost double the speed of the upper rollers, the mass of dough designated by 81 and 82 in its different positions is moved in a direction from the front to the rear end of the machine, but while being so moved it is pressed and kneaded by the upper rollers into a substantially helical form, the convolutions of which however, are pressed firmly together. At the same time the batch of dough is lengthened until its end con-y,

tacts with the side plates and it is thus converted into a spirally wound loaf which is uniformly kneaded and shaped and smoothed'on its surface by the rollers and emerges from between the rear end rollers P and W. When the rolled loaf is acted upon by the roller F of the group of three rollers G, E and F in the swinging frame 35 its diameter is so great as to tend to raise the roller F as shown in Fig. 5 whereby the front roller D of this group of three rollers D, E and F is forced downward and thus brought into the path of the fixed sheet of dough so as to curl or turn the inner end of said dough sheet.

It will be observed that the rollers of the upper tier with the exception of the feed roller can yield, for example, the three roll- ,ers D, E and F can swing upward together with the frame supporting them and can swing on the frame and likewise the frame 22 in which the upper rollers K, L, M, N, O and l. are mounted can swing upward with said frame so that when a thicker loaf is passed through the machine the upper rollers can yield to permit the passage of such loaf. Likewise when the frame 35 is raised by a passing loaf its upwardly projecting part 85 strikes against the forward end of the frame 22 and lifts it and all the rollers in said frame to form a larger passage way for the loaf.

Having described my invention what I claim as new and desire to secure by Letters Patent is Y 1. In a loaf forming machine, the combination" with a pair of feed rollers rotating in opposite directions, of a tier of upper ,and a tier of lower rollers, some of which rollers of the upper and the lower tier are constructed to beshortened or lengthened,
